Application January 18, 1949, Serial No. 71,507

1 Claim. (01. 115-5) My present invention relates to an improved pendulum driven hydraulic motor boat propulsion of the type especially adapted for use in small boats wherein the motor may be attached to the stern board of the boat to actuate a fluid motor and a propeller thereon.

The pendulum is swung by the motion of the boat upon the Water which will rock the boat except when the water is dead calm.

The pendulum driven motor includes a crank shaft which is oscillated to oscillate an opposed. blade compressor in the motor which from alternate chambers forces the fluid to the hydraulic motor to rotate the rotor and the shaft and propeller operably attached thereto.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised, but it will be understood that various changes and alterations may be made in the exemplified structure within the scope of the appended claim.

In the drawings:

Fig. 1 is a side elevational view of the assembled pump and motor.

Fig. 2 is a rear elevational v ew Fig. 3 is a front view of the pump at line 3-3 of Fig. 1.

Fig. 4 is a longitudinal sectional view through the pump.

Fig. 5 is a transverse sectional view of the pump at line 5-5 of Fig. 4.

Fig. 6 is a longitudinal sectional view of the motor.

Fig. 7 is a transverse sectional view of the motor at line l--'| of Fig. 6.

valves 44 pressed by springs 46 into seats 48 and these vanes of course reciprocate as the shaft and sleeve oscillates.

Arcuate plates 50 bisect the plates 36 and 38 and form chambers 52 and 54 communicating through holes 56 and 58 with the central chambers B0 and 62 in which the vanes reciprocate.

Each of the four chambers, 52 and 54, has an elbow 64 and 68 providing for the outflow and return of fluid, such as oil, therein.

On the lower end of post I2 in bracket 10, I secure a cylinder housing 12 having end plates Hi and 76 in which is journaled at T! the shaft 78 secured rearwardly by packing collar 8!] and a propeller 82 is secured on the shaft 78 by nut M and cotter pin 86.

Sleeve bearings 88 have disks 9!! centrally aligning the bearings for the shaft 18 and alternating with the sleeve bearings and disks I employ two fluid transmission assemblies including the free rotors 94 having radial vanes 95 on ring 97 and the hose sections from the motor are connected in bosses 98 by nipples I00 to admit and discharge oil under pressure. The vanes and ring have a peripheral flange l 02 forming a central chamber and in this chamber I use a disk late with rocking motion of the boat, a toggle acting spring connecting the pendulum to the UNITED STATES PATENTS blade, a, fluid motor housing carried by the Number Name Date bracket, a propeller carried by the fluid motor 44,963 Lawrence 8 1864 housing and positioned to be immersed in Water 5 249 499 Bouvier Nov. 1881 in which the boat is positioned, means connect- 624348 Lighthau May 1899 ing the horizontally disposed cylinder to the 2418637 Hamsty 81947 fluid motor housing whereby fluid under pressure provided by the blade in the horizontally dis- FOREIGN PATENTS posed cylinder actuates the fluid motor and pro- 10 Number Country Date pener- 209,126 Great Britain Dec. 18, 1923 IVAN E.
